What Lykn Learned from Other Languages
Lykn’s design draws from a specific lineage. No idea is original; every idea is composed.
From Scheme: the irreducible core. Five primitive forms from which everything else derives. Lykn’s kernel follows this: a small set of forms that map to JavaScript.
From Common Lisp: keywords (:name), the colon-package convention adapted to obj:prop. Practical macros — defmacro style, not syntax-rules.
From Clojure: threading macros (->, ->>), immutability by default, atoms (renamed to cell), the ! convention for mutation. Keywords as data.
From Erlang/LFE: multi-clause function dispatch. Pattern matching. The functional commitment. The thin-skin-over-host philosophy — LFE over BEAM, Lykn over JavaScript. Duncan’s direct heritage as an LFE contributor.
From Rust: Cell<T> naming, Option/Result types, exhaustiveness checking. The “make illegal states unrepresentable” philosophy.
From Fennel: thin-skin-over-Lua as proof that the approach works. No runtime. Compile-time macros. Small compiler. Clean output.
From JavaScript itself: ESTree, ESM, async/await, the event loop, template literals, destructuring. Lykn doesn’t fight JavaScript — it embraces its good parts and constrains its hazardous ones.
